A Brief Timeline of LGBTQ+ History and Mental Health in the UK

It's LGBTQ+ History Month, a time to reflect on the long and complex journey of LGBTQ+ people in the UK.

From criminalisation and forced psychiatric treatments to activism and progress, these events show how far we have come and the work that still remains. The world can feel like a scary place. For many LGBTQ+ people, especially trans people, it can be exhausting just to exist when rights are under threat. At Mental Health Matters, we want you to know that you are not alone. We welcome you, we listen, and we are here to support you. You deserve to live a meaningful life, be fully seen, and be celebrated for who you are.
